To all whom it may concern:

Be it known thatwaflfimiv EMU. FAGERw sTRoM, railway station-master,I-Iusqvarna, Sweden, ANDERS EDVARD J OHANSSON, manufacturer, Gisebo,Sweden, and GOTTFRID STREIJFFERT, merchant, Malmo, Sweden, subjects ofthe King of Sweden, have invented certain new and useful Improvements inClosing Devices for Bottles or other Vessels, of which the following isa specification, reference being made to the accompanying drawing.

The present inventionrelates to such devices for the closing of bottlesor other vessels in which the closing part, or stopper, is permanentlyattached to the neck of the vessel by means of a link device, and'whichstopper, by means of another device, is locked fast on its seat, whichis arranged in the neck of the vesse The object of the invention is toobtain an elastic, and at the same time, a good and secure tighteningbetween the stopper and its seat, by the employment of a stopper ofglass or other suitable hard material, whereby the use of rubber ringsor disks, which are objectionable in hygienic respects, is avoided. Thisobject is attained, partly by making the locking device (or said deviceand the link device) elastic in the longitudinal direction of the neckof the vessel, so that the said device (or devices) will hold thestopper against its seat with an elastic pressure of sufficient force,and also partly by giving the stopper a spherical form, so that the samecan, while bringing about a good and secure tightening, take up anyposition on its seat (within that space within which its movement islimited by the link). 7

On the accompanying drawing there are shown, as examples, two closingdevices or stoppers constructed in accordance with this invention andattached to necks of bottles.

Figures 1 and 2 show the one device, seen from two directions which areat right angles to each other, while Figs. 3 and 4 show, in the sameway, the second device and Fig. 5 is a rear elevation of the inventionillustrating the employment of I an elastic link for the stopper. In theform of construction shown in Figs. 1 and 2 the stopper 1 is in theusual way permanently attached to the bottle neck or head 2 by means ofa wire bow 3, a strip of sheet iron emer e "other-device. To "the headerthe bottle there is, as usual, pi-votalliy atvention, of a spiral spring6, which at its one end is pivotally attached to the lever and at theother end is integral with the bow.

As is shown, the closing or tightening part 7 of the stopper 1 is of aspherical form, which circumstance, together with the elastic pressurebrought about by the spiral spring 6, causes a good and secure tighten-I .7 In the closing device shown in Figs. 3 and,

4 the bow 5 and the spiral spring 6 are replaced by a bow 6 which isshaped somewhat like an 8. In consequence of the shape mentioned thislocking part is, as the spiral spring 6, elastic in the longitudinaldirection of the neck of the vessel.

It is clear that the locking device and the link device cansimultaneously be elastic in the longitudinal direction of the neck ofthe vessel. An elastic construction of the link is illustrated in Fig.5, the link 3 being shown as somewhat 8-shaped.

The elasticity of the locking device or the link device can evidently begained by the help of other arrangements than those shown.

Having now described our invention, what we claim as new and desire tosecure by Letters Patent is 1. In a device of the character described,the combination with the neck of a bottle, of a stopper having aspherical bearing surface adapted to seat in the bottle mouth, a bowelastically yieldable longitudinally of the bottie for pivotallysecuring the stopper to the bottle, and elastically yielding lOGKlllgmeans for locking the stopper on its seat.

2. In a device of the character described, the combination With the neckof a bottle, of a stopper having a spherical bearing surface adapted toseat in the bottle mouth, means elastically yieldable longitudinally ofthe bottle for pivotally securing the stopper to the bottle, and meanselastically yieluable longitudinally of the bottle for locking thestopper to its seat.

In Witness whereof we have hereunto set our hands in presence oi twoWitnesses.
